– What is Kubernetes? Kubernetes is a open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. The name Kubernetes originates from Greek, meaning helmsman or pilot. Kubernetes was developed by google in go-lang and open-sourced the Kubernetes project in 2014. – Why Do we need Kubernetes? Containers are a good way to bundle and run applications. Kubernetes manages the containers that run the applications and ensure that there is no downtime. – Benefits of

What is Kubernetes? Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available. You can cluster together groups of hosts running Linux® containers, and Kubernetes helps you easily and efficiently manage those clusters. Kubernetes clusters can span hosts across on-premise, public, private, or hybrid clouds. For this reason, Kubernetes is an ideal platform for hosting cloud-native applications that require rapid scaling,

What is Kubernetes? Kubernetes is a platform for managing a multi- container based deployment for distributed workloads for APP and services, Why Do we need Kubernetes? Main rational is to to achieve scalability and load balancing and fault tolerance by ensuring availability of all distributed nodes of application. It is more portable and extensible such that it would also speeds up the delivery process and provides better resource management. This concept would also be easily adoptable for cloud based deployments.

What is Kubernetes? Kubernetes is an open source orchestration tool developed by Google for managing microservices or containerized applications across a distributed cluster of nodes. Kubernetes provides highly resilient infrastructure with zero downtime deployment capabilities, automatic rollback, scaling, and self-healing of containers (which consists of auto-placement, auto-restart, auto-replication , and scaling of containers on the basis of CPU usage). Why Do we need Kubernetes? Containers are a good way to bundle and run your applications. In a production environment, you

– What is Kubernetes? Kubernets also called as K8s is a framework to manage multiple containers automatically by providing facilities like load sharing, aotu scalling, self healing etc. With help of either JSON or Yaml we can state our desire to Kubernet and it can be done without any manual intervention. – Why Do we need Kubernetes? We need Kubernets becuase of below reasons:- load balancing Storage Orchestration Self healing – Benefits of kUbernetes? As stated in above pointers, if

What is Kubernetes?Kubernetes, or k8s, is an open source platform that automates Linux container operations. It eliminates many of the manual processes involved in deploying and scaling containerized applicationsIn other words, you can cluster together groups of hosts running Linux containers, and Kubernetes helps you easily and efficiently manage those clusters. Why Do we need Kubernetes? Benefits of kUbernetes?Kubernetes eases the burden of configuring, deploying, managing, and monitoring even the largest-scale containerized applications. It also helps IT pros manage container

What is Docker and Container? Docker image is blueprint of the container (application files + dependencies + filesystem), where as container is running instance of that imageDocker image is created once and multiple Container instance can be created from same imageDocker image just requires disk space as its logical , where as container instance requires computation resource + memory space Containers also isolate applications from each other on a shared OS Difference between docker pause and unpause? The docker pause

Assignment# 1 – What is Docker and Container? Define in 15 points with example image Docker:- is a tool which manages Containers and it provides industry a const efficient , time efficient and quality infrastructure. Docker is a utility built on top of kernel which is responsible to allocate resources from main system which is used by Containers. Dockers basically talks to kernel as per User requests and creates below core resources from kernel Namespace which will be used by

Update The docker update command dynamically updates container configuration. You can use this command to prevent containers from consuming too many resources from their Docker host. Examples: docker update –cpu-shares 512 23263ad49893 Wait Block until one or more containers stop, then print their exit codes. Examples: start the container in background docker run -dit –name=poorani1 bash wait for the container docker wait poorani1 stop the container in another terminal or console docker stop poorani1 container wait command will get the exists

1. What is Docker and Container? Define in 15 points with example image. Docker is an open source platform tool for building, deploying, and managing containerized applications. Containers are an abstraction at the app layer that packages code and dependencies together. Multiple containers can run on the same machine and share the OS kernel with other containers, each running as isolated processes in user space. 2. What is the difference between docker pause and unpause? The docker kill, docker stop

Assignment# 1 – What is Docker and Container? Define in 15 points with example image Container: Container in short a runtime of it’s own Runs in separate namespace isolated from host Has its own Root FS & USER space, PID tree, MNT and Network etc. This is not a bootable image like VM and BOOT FS is held with host itself. Its own quota of Resources like RAM, CPU etc would be Allocated through cgroups Docker: Container manager SW that

Assignment# 1 – What is Docker and Container? Define in 15 points with example image Docker: Docker is container management platform There are two major Docker components – Docker Engine and Docker Image Docker Engine is a collection of Docket client, service Docket container is collection of ContainerD service and interface to Kernel services Docker Image is a collection of file systems and versions of file systems Docket images contains ROOT file system + User file system and Application file

What is Docker? Docker is container management tool. Docker has two release. Enterprise Community. Father of Docker is solomna hykes. It’s written in Golang. Latest version of Docker is 20.X 2. Container Container is runtime application environment where we can run the application. lightweight and has no OS , Kernel. Which has all resources to run which comes from root machine, independent run time environment and isolated. 3. Difference between docker pause and unpause? Docker pause Docker unpause Suspends all

A Secret is an object that contains a small amount of sensitive data such as a password, a token, or a key. Such information might otherwise be put in a Pod specification or in a container image. Using a Secret means that you don’t need to include confidential data in your application code. A kubernetes.io/service-account-token type of Secret is used to store a token that identifies a service account. When creating a Pod, Kubernetes automatically creates a service account Secret and automatically modifies your Pod to
